Bell Telephone Company transmits a speech by
U.S. Secretary of CommerceHerbert Hoover 320 kilometers over telephone lines, which becomes the first successful long distance demonstration of television. Experimental station
3XN in
Whippany, New Jersey is used to transmit 1,575
kHz video and 1,450 kHz radio. The system uses a flying-spot scanner, and is seen on Nipkow disc receivers with two-inch, 50-line images, and on a two-foot neon tube display. It was developed by
Herbert E. Ives and Frank Gray. Edna Mae Horner, an operator at the
Chesapeake and Potomac Telephone Company, assisted the transmission and became the first woman on television; she helped guests in Washington, D.C., exchange greetings with the audience in New York
[1]. Throughout the presentation, viewers in New York could see and hear Edna
